Vim sugar for the UNIX shell commands that need it the most. Commands include:

* :Unlink: Delete a buffer and the file on disk simultaneously.
* :Remove: Like :Unlink, but doesn't require a neckbeard.
* :Move: Rename a buffer and the file on disk simultaneously.
* :Chmod: Change the permissions of the current file.
* :Find: Run `find` and load the results into the quickfix list.
* :Locate: Run `locate` and load the results into the quickfix list.
* :SudoWrite: Write a privileged file with sudo.
* :Wall: Write every open window. Handy for kicking off test autorunners.
